[PATCH v6 1/5] perf: build: introduce the libcapstone
From: Changbin Du
Date: Mon Feb 05 2024 - 21:15:30 EST
Later we will use libcapstone to disassemble instructions of samples.
Signed-off-by: Changbin Du <changbin.du@xxxxxxxxxx>

v3:
- display with perf version --build-options. (Adrian Hunter)
- exclude libcapstone from make_minimal.
v2:
- change tools/perf/tests/make also.
